Abstract: Robust temporal gradients, representing differences in shading results, can be computed between current and previous frames in a temporal denoiser for ray-traced renderers. Backward projection can be used to locate matching surfaces, with the relevant parameters of those surfaces being carried forward and used for patching. Backward projection can be performed for each stratum in a current frame, a stratum representing a set of adjacent pixels. A pixel from each stratum is selected that has a matching surface in the previous frame, using motion vectors generated during the rendering process. A comparison of the depth of the normals, or the visibility buffer data, can be used to determine whether a given surface is the same in the current frame and the previous frame, and if so then parameters of the surface from the previous frame G-buffer is used to patch the G-buffer for the current frame.

Abstract: A virtual reality (VR) system comprising a head-mounted display (HMD) and handheld controller set is enhanced to provide a more realistic end user VR experience, e.g., for generalized surface interactions in the VR environment. The techniques herein leverage controller-less calibration with any type of surface, followed by surface interactions in the VR environment. An example use case is an interactive fitness training session.

Abstract: For multi-view video content represented in the MVD (Multi-view+Depth) format, the depth maps may be processed to improve the coherency therebetween. In one implementation, to process a target view based on an input view, pixels of the input view are first projected into the world coordinate system, then into the target view to form a projected view. The texture of the projected view and the texture of the target view are compared. If the difference at a pixel is small, then the depth of the target view at that pixel is adjusted, for example, replaced by the corresponding depth of the projected view. When the multi-view video content is encoded and decoded in a system, depth map processing may be applied in the pre-processing and post-processing modules to improve video compression efficiency and the rendering quality.

Abstract: Techniques for aligning images generated by two cameras are disclosed. This alignment is performed by computing a relative 3D orientation between the two cameras. A first gravity vector for a first camera and a second gravity vector for a second camera are determined. A first camera image is obtained from the first camera, and a second camera image is obtained from the second camera. A first alignment process is performed to partially align the first camera's orientation with the second camera's orientation. This process is performed by aligning the gravity vectors, thereby resulting in two degrees of freedom of the relative 3D orientation being eliminated. Visual correspondences between the two images are identified. A second alignment process is performed to fully align the orientations. This process is performed by using the identified visual correspondences to identify and eliminate a third degree of freedom of the relative 3D orientation.

Furthermore, a virtual image (310) is generated based on the determined second image.
